How chemists quantified acidity and basicity through the pH scale

ISS experiments produce metal alloys and composite materials with properties impossible on Earth, advancing aerospace, electronics, and clean energy.

ISS experiments with brain organoids and amyloid-beta protein reveal how microgravity reshapes neural aging and protein folding, opening a new research platform for Alzheimer's disease.

July 20, 1969: Neil Armstrong and Buzz Aldrin landed on the Moon, returning 21.5 kg of lunar samples that revealed the Moon's geological history and transformed planetary science.

December 1972: Apollo 17 landed at Taurus-Littrow, returning 110.5 kg of samples and conducting 22 hours of moonwalking—the most scientifically productive lunar mission.

Apollo astronauts left reflectors on the Moon allowing scientists to measure Earth-Moon distance with millimeter precision—revealing the Moon's orbital evolution.

ISS experiments reveal that bacteria behave differently in microgravity, becoming more virulent and developing antibiotic resistance faster—with surprising implications for spacecraft safety and planetary protection.

Spaceflight produces aging-like changes in bone, muscle and the cardiovascular system, most of which largely reverse after return. Here is what the NASA Twins Study and ISS research do, and do not, show about aging.

ISS astronauts lose bone density faster than aging populations, revealing mechanisms of osteoporosis and informing prevention and treatment strategies.

ISS experiments reveal that cancer cells behave differently in microgravity, sometimes becoming more aggressive but also more vulnerable—insights accelerating cancer research.

ISS research reveals how weightlessness causes fluid shifts, cardiac deconditioning, and blood flow changes—insights applicable to heart disease treatment on Earth.
